To aZZ whom, it may concern:

Be it known that I, GEORGE M. GnIswoLD, residing at New Haven, in the county of New Haven and State of Connecticut, havcinvented certain new and useful Improvements in Machines l'or Making and Printing Tubes or Shueks for Paper Boxes; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in machines for making and printing tubes or shacks for paper boxes, the object being to produce a machine of simpie and durable construction, efficient in operation, having a large capacity for work, and adapted for the employment of ordinary electrotypes.

"With these ends in View my invention consists in certain details of construction and combinations of parts, as will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is a view thereof in side elevation. Fig. 3 is a similar view from the oppositc sideoi' the machine. Fig. 4 is a similar rear view of the machine. Fig. 5 is a similar front view thereof. Fig. 6 is a viewof the machine in central vertical longitudinal section. Fig. 7 is a reverse plan view of the inkdistributing dial. Fig. 8 is a plan view thereof with the ink-fountain. Fig. 9 is a detached view of the printing-platen. Fig. 10 is a sectional view thereof. Fig. .11 is a detached view in side elevation of the rocking frame. Fig. 12 is a view in side elevation of the operating connections of the ink-roll. Fig. 13 is a plan view of a tube-blank. Fig. 14 is a view in end elevation of the folded strip, and Fig. 15 is a perspective view of a tube.

The stock A is prepared in long strips of the required width and rolled into a coil upon a spindle, B, removably mounted in brackets G O, secured to the frame D of the machine at the rear end thereof. From such coil the end of the strip passes upward and between two small guide-rolls, E E, and thence between a large roll, F, having a rubber or other cuslr inning surface, G, and located below the strip, and four creasing-disks, l lf, located above the same and journaled in the lower ends of four frames, 1, made vertically and laterally adj ustable in a cross-piece, J, supported at either end in arms K, secured to the bed L of the machine. This creasing operation virtually divides the strip into five longitudinal divisions, (designated by M, N, O, P, an d Q. and clearly shown by Fi 13 of the drawings.) The strip passing forward has the under face of its division M, which is the narrowest of all, con tinnously gunimed by a narrow disk, It, journaled in a glue-pot, S, located in a. water-pot, T, intersected by a steam-pipe, U, as shown. The strip is held in place while being gum med by threesmall rollers, V, jou rnaled in the lower ends of adjustable spindles \V, mounted in the cross-frame X of the machine. Passing forward of the rollers V the divisions M and N on one side of the strip and the division Q on the other side thereof are gradually lifted until they stand upright against the outer faces, respectively, of two rollers, YY, located above the strip, journaled in the lower ends of adjustable spindles Z Z, mounted in the crossframe A, and having their outer edges located just on the onteredges 0f the sections 0 and P, which they prevent from folding and keep undisturbed on the bed of the machine. Passing these rollers last mentioned the lifted sections of the strip fall over within the lines of the middle divisions thereof and are entered with the divisionsM and N beneath,and the gnmmed face of the former uppermost, and the division Q lapping over it under the parallel formers B B,which are movable toward and away from each other to produce shocks or tubes of different sizes, and are thereto provided each with bolts ac, playing in transverse slots Z) 11, formed in the bed of the machine, the formers being secured in their several adjustments by the said bolts. Directly in front of the forward ends of these formers are located the feedrolls O O, which by drawing the strip under the formers operate to lift its edges and fold them in the manner specified. The shafts of the feed-rolls are each provided at one end with a pinion, D, such pinions intermeshing, and the lower pinion also intermeshing into a pinion, E, having in its outer face a circular groove, F, receiving a pawl, G, )lVOtCd to a link, H, the latter being also connected with the upper end of a lever, I, fulcrnined upon the shaft J of the pinion, and having its lower end connected by a lever, K,with a stud, L, movably mounted in a transverse slot,M, in awheel,N, mounted upon a shaft, 0, the opposite end of which carries a gear, 1?, meshing into an intermediate gear,Q, carried by a shaft, R, also carrying the pulley S, through which the machine is driven. When in the revolution of the wheel N the upper end of the lever I is thrown back, the pawl G and link H at once cramp and couple thelever and the pinion E together, whereby the latter is turned and the feedrolls actuated in feeding forward the strip. When, on the other hand,the revolution of the wheel N moves the upper end of the said lever forward,the pawl and link slip in the groove and no actuation of the pinion and feed-rolls occurs. Such feeding connections are timed to impart an intermittent forward movement to the strip and are susceptible of very close adjustment in the amount of feed.

The strip folded, gummed, and compressed is fed from the feed-rolls under a printingplaten, T, supported in the frame of the machine, and provided upon its under face with a rubber cushion, U, the opposite ends of which are inserted into slots V V, extending across the platen, as shown, and receiving cam-shaped keys W W, adapted to be turned and to take up and hence tighten the said cushion. I The strip is printed upon its under face by type carried upon a bed, X, located upon the upper edge of a horizontal carriage, Y, having its opposite ends entered into vertical slots Z Z, formed in the foremost uprights of the frame, such carriage being vertically reciprocated through a crossbar, A, passing under it and through the slots in the uprights and engaging with its lower edge. Pitmen B B, pivoted to the projecting ends of the said cross bar, are eccentrieally pivoted at their upper ends to wheels 0 O, mounted on a shaft, D, one of such wheels being a gear-wheel and meshing with the gear Q aforesaid. The carriage Y is not carried through the full length of the stroke of such levers, but is supported in position for the inking of the type, while the cross-bar is carried to the lower ends of the slots Z Z by studs E E, projecting from it and engaging with blocks F F, secured to the uprights, as shown. In the downward movement of the said cross-bar it leaves the carriage when the studs thereof engage with the blocks, and in its upward movement lifts it from such point, the time occupied by the cross-bar after it leaves the carriage in traveling to the limit of its downstroke and then back to the carriage forming the interval of rest required in the same for inking the type upon the platen.

The type are inked by rollers G G, mounted in a carriage, H, located between guideways 1 I and connected at its rear end through links J J with the respective arms K K of a rocking frame, L, supported in the frame of the machine and connected through rigid levers M, N, O and I? with a cam-groove, Q,

formed in the outer face of the gear P, before mentioned, the said frame being rocked back and forth by these connections and imparting a reciprocating motion to the ink-roller carriage H, which normally rests upon the inkdistributing dial R, mounted in the frame of the machine and provided upon its lower face with a hub, S, and a ratchet, T. The said ratchet is engaged by a pawl, U, carried by a lever, V, (see Fig. 7 connected through levers W and X with a rod, Y, passing through a hole, Z, in the rocking frame L and provided upon opposite sides of the same with adjustable nuts A A, with which the frame engages to move the rod and, through the levers W and X, actuate the pawl and dial, the nuts being adjusted so that the dial is rotated in the interval when the inking-rollers and their carriage have left it for inking the type.

The inking-rollers G G are inked by the engagement or contact of the rear roller of the two during the rearward movement of the carriage H with the ink-roll B, journaled in the forward end of the fountain O, the same being pivotally mounted in the frame of the machine and vertically adjustable through the screw D, and the amount of ink taken up by the inkroll being regulated by the pressure against it of a plate, E, through screws F, as shown. The said ink-roll is provided at one end with a ratchet-wheel, G, (see Fig. 12,) engaged by a spring-actuated pawl, H, carried by a lever, I, fulcrumed upon the shaft J of the roll and ratchet and connected at its lower end with a rod, K, extending through an opening, L, in the rocking frame L, and provided on the opposite sides of the same with adjustable nuts M, which are engaged by the frame, whereby the rod, lever, and pawl are actuated in turning the roll.

The strip is cut up into short tubes just before being printed by a knife, N, rigidly secured to the forward end of the platen T and cooperating with a knife, 0, secured to a carriage, 1,frictionally supported (with a ca pacity for vertical movement) in Vshaped slots Q, formed in the inner faces of two upright frames, It R, respectively secured to the foremost upright of the frame of the machine. The said knife-carriage is lifted for cutting off the slides from the strip by the engagement with its lower edge of a verticallyadjustable arm, 0, secured to the outer face ofthe carriage Y, as the same is lifted in printing the under side ofthe strip. The knifecarriage, being frictionally supported, remains where it is leftby the arm 0 and is forced down again to give clearance to the strip which is fed over it by cams S S, mounted upon the shaft D and engaging with framesT T, secured to the carriage, as shown, the said cams being timed to give clearance to the frames when the knifecarriage is lifted, as described.

Under the described construction I am ohabled to employ ordinary electrotypes with obvious economy and advantage.

I would have it understood that I do not IIC limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a papcrbox machine, the combination, with folding and gumming mechanism, sub stantially as described, to fold the edges of a stock-strip over upon its upper face and to gum one of its edges which are overlapped, of a vertically-reciprocating type-bed carriage located below the strip in position for printing the folded and gunimed end thereof, whereby the type is isolated from the gum, a movable cutter located outside of the said carriage and below the strip, inking apparatus located below the strip, and a platen and a stationary cutter located above the strip, substantially as set forth.

2. In apaper-box machine, the combination, with folding and gumming mechanism, sub stantially as described, to fold the edges of a stock-strip over upon its upper face and to gum one of its edges which are overlapped, of a vertical]y-reciprocating type-bed carriage located below the strip in position for printing the lower face of the folded and gumnied end thereof, whereby the type is isolated from the gum, a platen located above the strip and over the said bed, a vertically-reciproeating cutter located below the strip and outside of the said carriage which intermittently lifts it, a stationary knife located above the strip and outside of the platen and cooperating with the said movable knife, and means, substantially as described, located above the strip for depressing the cutter to let the strip pass over it, substantially as set forth.

3. In a paper-box machine, the combination, with folding and gumming mechanism, substantially as described, to fold the edges of a stock-strip over upon its upper face and to gum one of its edges which are overlapped, of a vertically-reciprocating typebed carriage located below the strip in position for printing the lower face of the folded and gummed end thereof, whereby the type is isolated from the gum, a platen located above thestrip and over the said bed, a vertically'reciprocated frictionally-supported outterlocated below thestrip, a stationary cutter located above the strip and outside of the platen, frames connected with the movable cutter, and cams located above the strip and engaging with the said frames to depress the movable cutter to allow the printed strip to pass over it, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
